I personally believe they are fake, or at least I hope they are. BUT, I registered to say:
Some of the "proof" that has been used to show they are fake, is not adequate proof.
First the feet of lickilicky and Pignit2 are NOT the same. They right one is angled completely differently, and the left is just different, also the stomach of Pignit2 is more "perky" Ha. It is more angular as opposed to Lickilicky's round stomach.
Second, It is possible for there to be minor discrepancies between two different drawings. Its not unlikely for them to not be exactly the same. That said, the Gif posted, is not good proof. The rounded vs. Pointy ears is just a possible difference between two different drawings. The mouth argument just plain sucks. There is a measurement line going through the mouth, this causes the mouth to not be clear and besides the beta art is not clear enough to compare those mouths.
All this said, I still don't think they are real. I don't think they look like sugimori's style, f they are supposed to be from the anime, then I do not know... but I sure hop not.
I don't exactly see what your point on that is? So they were copied onto the background, there are a number of reasons that that could have been done. Of the http://www.errorlevelanalysis.com/permalink/2b28a9f/ that is
If you mean the possible reason for why they could be copied, well they could have been on another sheet with other Pokemon then copied over to the background. Also Zaykorz seems to have some experience with it (of which I have none) and he seems to think they're either printed or real.
